The 74AHC/AHCT595 are high-speed Si-gate CMOS devices and are pin compatible with Low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard No. 7A. The 74AHC/AHCT595 is an 8-stage serial shift register with a storage register and 3-state outputs. The shift register has separate clocks. Data is shifted on the positive-going transitions of the SHCPinput. The data in each register is transferred to the storage register on a positive-going transition of the STCP input. If both clocks are connected together, the shift register will always be one clock pulse ahead of the storage register.
APPLICATIONS • Serial-to-parallel data conversion • Remote control holding register.
Feature
• ESD protection: HBM EIA/JESD22-A114-A exceeds 2000 V MM EIA/JESD22-A115-A exceeds 200 V CDM EIA/JESD22-C101 exceeds 1000 V • Balanced propagation delays • All inputs have Schmitt-trigger actions • Inputs accept voltages higher than VCC • For AHC only: operates with CMOS input levels • For AHCT only: operates with TTL input levels • Specified from−40 to +85°C and from−40 to +125°C.
